SPECIFICATION forming part of Letters Patent No. 549,519, dated November 12, 1895. Application ned June 24,1895. serial N0.`s,917. No moda.)

To all whom t 12v/ay concern:

Be it known that I, PHILIP H. MAGUIRE, a citizen of the United States, residing at Battle Creek, county of Calhoun, and State of Michigan, have invented certain new and useful Improvements in Pneumatic Stackers, of which the following specification contains a full, clear, and exact description, reference being had to the accompanying drawings, in which- Figure l is a perspective view showing the chute in the position it occupies when not in use. Fig. 2 is a similar view showing the chute in its operative position on the turn-table. Fig. 3 is a detail in section showing the inner hinged end of the chute and the doors closing the joints. Figs. 4, 5, 6, and 7 are other de tails. j

The invention relates to pneumatic stack ers; and the obj ect of the invention is to provide the tubular chute with a carriage adapted to register with a track along the top of a grain separator or thrasher, one section of the track being on the horizontal turn-table, which has an opening registering with the straw-outlet of the thrasher and with the elbow at the inner end of the chute, so that theV a whole, and also for operating it telescopically. v

The invention will be irst described, and then specifically pointed out in the claims.

In the drawings, A represents the top 'por tion of a thrasher or grain-separator casing, provided with a turn-table B at its Vrear end, which has an opening b, registering with the straw-outlet A in the top of separator-Casin g, through which outlet the straw is forced, as usual, by means of a blast of air from a suit- (Not shown. This turntable B is held in place by means of a circularly-arranged series of angle-brackets b', engaging the wall of the opening b therein and overlapping the upper side of the turn-table,

as shown best in Fig. 6. These angle-brackets b are secured at their lower ends to the top of the depressed rear end of the machine frame or casing, and the turn-table revolves freely upon them as its axis (see Fig. 5) in the usual manner. The exterior of the turntable is formed as an operating-wheel B', which may be plain or toothed and operated in any suitable manner by means of a belt or gearing.

On top of the turn-table are parallel tracksections or guideways C C', which register with the rear ends of the main tracks or guideways C C, of any suitable construction, upon the top of the casing A. These tracks and sections are provided with channels or guideways c in their adjacent faces, which receive the side edges of the carriage D, which carries the tubular chute E, and the rear ends of the tracks C C are cutaway or beveled, as at c', to permit the ends of the track-sections C C to pass them when the turn-table B is rotated. The forward end of the'turn-table B is provided in its upper side with a stop b2 to engage alug or projection d2 on the lower side of the forward end of the carriage D and limit the rearward movement thereof.

The carriage D is provided with wheels d, which run on the lower ange of the tracks.

The chute E has a stationary section or elbow E at its inner end, which is secured to the upper side of the carriage, over an opening therein, which opening registers with the opening o of the turn-table when the carriage is in place thereon, and to the upwardly-extending side ears e e of the section or elbow E are pivoted similar ears at the inner end of the vertically-swinging chute-section E2.

-The openings at the upper and lower sides of the joint between the sections E E2 are closed by the doors e e', which are hinged to the section E and extend at their free ends into the top and bottom of the rear end of section E2 and permit it to be freely adjusted at any desired angle. The upper door c rests on the upper edges of the side ears e c, which prevent it from falling and hold it in contact with the upper side of the section The pivoted or hinged end of the chutesection is provided with pins e2 through the medium of a strap c3, which encircles said section and has its ends connected by a bolt c4.

IOO

The pins c2 extend through slots f in the side arms of a standard E, pivoted at its lower ends to the carriage D and provided at its upper end with a pivoted arm F,connected at its free upper end with the upper side of chute-section E2 by means of a rod f'. These pins c2 and slots f limit the vertical movement of the chute E and also assist in steadying it.

G is a drum mounted on the carriage and provided with an operating cord or cable g, which is connected with the upper end of the 'arm E and b y means of which the chute E may be raised and lowered. The drinn G is provided with an operatingcrank and a ratchet g, engaged by a pawl g2, so that the parts will be held in their adjusted positions.

The outer sliding section E3 of the chute E is provided with a forward strut or brace f2, secured at its forward end to an eye f3 and at its rear end to a standard f4, and f5 is a similar brace or strut secured at one end to adjacent end of forward strut f2 or its standard f 4 and having a sliding connection at its opposite end, through the medium of an eye f, with the rod j", thus permitting the sliding movement of chute-section On the upper side ot` the chute-section E2 are secured two parallel wires II, terminating at their rear ends in an eye 71 to which the forward end of rod f is secured, and at the forward end of the channel formed between said wires is pivoted a horizontal guide-pulley 71. The rear end of the sliding' chuteseetion has an opening ci in its upper side, and adjacent thereto is secured the eye e for a purpose which will be presentlydescribed.

J represents a pair of arms secured by bolts j to the chute-section E2, and a shaft K is mounted in the upper ends of said arms and provided with an operating-crank 7c and a ratchet f, engaged by a pawl if?. Epen the shaft K are mounted two drums L L', the drum L being fast and the drum L bein g loose on the shaft, while the adjacent ends of the drums are provided with clutch-teeth I l. A cord or cable Z2 is wound on drum L and is connected to the eye e, while a similar cord or cable Z"s is wound oppositely upon the drinn L, and extends thence through the channel formed between the wires ll, around the guide-pulley h, and thence back through the opening e5 to the eye c, to which it is secured. Thus by operating the drums L L the outer chute-section E3 may be slid out and in, as may be desired, and the wires II will protect the cord or cable Z3 from Contact therewith and the wear incident thereto.

By reason of the clutch-teeth Y Z for operatively connecting the drums L L there need be no nice adjustment of the length of the cords l2 Z3.

In order to move the carriage D and its attached parts from the position shown in Fig. l to that shown in Fig. 2, and vice versa, I provide the two drums M M, mounted loosely on the shaft M2 and having clutch-teeth m m on their adjacent ends to alternately engage the clutch-teeth mt on the ends of the clutchsleeve M3, which sleeve is operated by the usual pivoted forked lever M4. Cords or cables m m7 are wound oppositely on the respective drums M M and extend therefrom in opposite directions to the ends of: the casing, where they pass around suitable guidepulleys m8, and thence to the respective ends of the carriage I), to which they are connected. The shaft M2 is always turned in the same direction and rotates whichever drum the sleeve M3 is clutched to, the other drum then unwinding.

The outer end of the chute-section E3 is eut away at its lower side and its edges are reinforced by a marginal strip E". Any suitable hood maybe secured to the said outer end, if desired.

\Vhen the machine is being driven from place to place or is not in use, the chute will occupy the position shown in Fig. l but when the scene of operation is reached the shaft M2 and drum M will be operated to draw the carriage D, with the chute E and its operatin mechanism, rearwardly upon the turn-table, when the chute will register with the strawoutlet in the casing. Then the drum G will be rotated to operate arm F and rod f till the chute is raised to the desired angle, and then the shaft 7c will be rotated to slide the chute-section E3 outwardly to any desired extent. The chute as a whole maybe swung sidewise through the medium of the turn.- table B and its operating-wheel B. \\hen the eye fG on strut-section f5 engages the eye at the outer end of the rod f, the section E3 of the chute will be held from further outward movement, and it is to brace the telescopic chute when thus fully extended that I provide the two-part brace f2 The sliding chute-section E3 being wholly exterior to the inner section E2 no internal shoulder will be formed to impede the passage of the straw.

Instead of forming the channel for cord or cable Z3 by means of the wires Il said channel may be formed by a groove directly in the chute-section E3 or by means of a tube or half-tube secured thereon.
